I'm looking for a machine to make bags and wallets with. A friend has an older Consew 206rb. Not sure if it's rb-1, 2, 3 or what. It's got white paint, so it's not the original 206rb. It's got a clutch motor and no speed reducer. He wants $800 for it. After I add a servo motor and/or speed reducer, it'll end up costing almost as much as a new machine. Should I buy it or buy something new? Looking at a Highlead GC0618-1S that I can buy new locally. I have not tried a walking foot machine at all, so I don't know what it's like to sew with either type of motor. I do know that I want to be able sew slowly. Thanks in advance for you help!
